How to Find Bed Bugs During the Day

Learning how to find bed bugs during the day is tricky. If you are wondering where bed bugs hide during the day, we will help out with some clues. We will help you figure out how to track bed bugs during the day.

As you can imagine, bed bugs prefer to be hiding in the dark, which is why they are most active at night. Anyone who has ever had an infestation will tell you that finding where bed bugs hide during the day is one of the more challenging aspects of fighting this problem. Sometimes even catching them in action is difficult because they usually feed on us at night. (see our exceptions below)

6 Things To Do To Help You Find Bed Bugs During The Day

  1. Hire a bed bug sniffing dog service. We here at Doctor Sniffs use dogs to help us find bed bugs during the day all of the time. Once our dogs are alert to bed bugs, we begin taking apart the bed or furniture near the spot, looking for evidence.
  2. Examine the seams of your mattress and box spring with a flashlight. You must inspect all six sides of each; you can do this by standing them up and carefully searching the seams. For the box spring, take off the stapled-on cover on the bottom. Looking inside the box spring, we often find bed bugs inside of the box spring. If you find any bugs or fecal matter, it may be bed bugs.
  3. Place out bed bug traps and monitors. You can check these during the day for activity. Use both active and passive monitors. If you see any fecal matter, live bugs, or shed skins, then you know you have a problem.
  4. Stand your bed frame up on its side. When you stand it up, be sure to look in every corner, crevice, and joint We often find bed bugs sitting underneath the bed frame.
  5. Inspect your headboard or picture frames above your bed. Bed bugs often hide behind the headboard, in a deep seam of the headboard, behind a picture frame, or somewhere similar. Look for black ink-like marks; you can buy a test kit to confirm if they are bed bug fecal droppings – Bed Bug Blue.
  6. Inspect all of the furniture in your room. Check all sides of any dressers or nightstands that you suspect to have a problem within the room. Do you have furniture next to the bed?

What To Do Right Away If You See A Bed Bug In Your Home During the Day

  1. Put on mattress and box spring encasements; however, it’s most important to use box spring covers. Box springs have a lot of wood inside; hence there are plenty of hiding spots.
  2. Put out traps and monitors.
  3. Follow the steps above for tips on finding them.
  4. Hire a professional.
  5. Some people treat their home when they see one bed bug, and other people monitor and wait until they find more.

Can You See Bed Bugs During The Day?

Yes, you can see bed bugs during the day for many reasons. You will often find bed bugs by looking for their fecal droppings since it’s black and smears when you rub them. If you have a lot of bed bug activity, it will be easy to spot black spots on your furniture, sheets, and pillowcases, as well as anywhere else they like to hang out. Most of the time, we can’t see bed bugs during the day, but we can find their droppings and shed skins.

If you can’t see bed bugs during the day, you may want to invest in a bright flashlight or bed bug traps. The traps are hidden and placed under your mattress or bed frame. They monitor for any movement and help you catch an infestation early. Put them under the bedposts, behind furniture, and alongside the molding behind your headboard. That is when we most often find them.

Reasons why you might see bed bugs during the day

  • You brought in a hitchhiker that is hungry and searching for a blood meal.
  • If you live within an apartment building, one of your neighbors may be self-treating. If someone is self-treating nearby, it can cause some bed bugs to migrate to your apartment.
  • You went on a trip and didn’t realize that you brought a bed bug home in your suitcase. However you may find the bed bug weeks later roaming around in your home looking for a blood source.
  • You just happened to disturb the bed bugs by changing a sheet, so now they are scattering.
  • The bed bugs live somewhere, like a couch or a chair, where there isn’t anyone sleeping at nighttime. In this case, we will see them begin to move around and feed in the daytime.
  • A bed bug issue is happening in your place of work. Since nobody is there at nighttime, you may see bed bugs wandering around on the office furniture in the daytime.

Are Bed Bugs Only Active At Night?

No, they can come out during the day if they are hungry. Often when people see them during the day, the bed bug is relatively flat, which means that it has not fed in a while and is out searching for a blood meal. Figure out whether your bed bug is a male or female bed bug, so you know if you need to worry about eggs.

Do Bed Bugs Bite During the Day?

Yes, bed bugs bite during the day if they are hungry, and it is a feeding opportunity.

We often see this behavior in an infested apartment building because there are so many bed bugs that some have to feed during the day to get enough food. We also find this when people bring in a straggler on their clothing. A third reason is that the bed bugs are living in a place where there are no people there at nighttime. Therefore in order to eat, they must bite during the day.

Are Bed Bug Eggs Visible?

Yes, a bed bug’s eggs are visible to the naked eye. The bed bug eggs are only 1mm in length and are white. They are oval-shaped and have a cap that opens to let the bug out when they are ready to hatch. However, an actual Bed bug is between 1mm and 5mm long before it feeds. They may get up to 6 or 7 mm when engorged with blood.

Bed bugs often prefer crevices where it’s easy to hide. So, using a ruler, you can see that bed bug eggs are pretty small and hard to find if they are on the surface of your mattress or furniture. The other thing about bed bugs is that they can squeeze into tight spaces. Anywhere you see two pieces of wood screwed or nailed together (like on a bed frame) is a potential place where they may be hiding.

When Are Bed Bugs Most Active?

They are nocturnal creatures and prefer to be active during the nighttime. However, if they are hungry enough, you will see them during the day.

Are Bed Bugs Active During the Day?

Yes, they can be active during the day, but that is not natural. Naturally, they are nocturnal and prefer to feed on blood at night.

What Does It Mean If You See A Bed Bug On Your Wall During The Day?

It usually means that you either brought in a straggler and it has not yet found its permanent home (your bed), or it’s wandering from a neighboring apartment. Sometimes we find an infestation so heavy that the bed bug is crawling on the walls, ceilings, and floors. Usually, when one apartment is this bad, the bed bugs begin turning up in neighboring units. So if you see a bed bug on your wall, you may want to insist that the management company inspect the adjacent apartments.

Check for any bats around your property. Sometimes random bugs on walls are mistaken for bed bugs when in reality, they are bat bugs. Zoom in and take a clear photo of the bug. Then send it to your local pest control professional for ID. Above all, getting rid of bat bugs requires first dealing with the bats.

What Does It Mean If I See A Bed Bug On My Comforter During The Day?

There are times when this happens, but it’s not normal. It could mean:

  • Sometimes if a person does not react to bed bugs, they do not know that they have a problem. Usually, the person will go away on a trip, and when they return home, they see a random bed bug on their bed in the middle of the day. More importantly, it’s because the bed bug did not have a regular blood meal, so it is out wandering looking for food during the day.
  • Another reason may be that you picked up a bed bug at the laundry mat. If you use a laundry service, there is a small risk that your clothing will contact a bed bug at the laundry mat.
  • Always make sure to ask them to dry your clothing in the hottest setting.
  • A third reason is that you went to the movies, Doctor’s office, or some other public place with an unknown bed bug issue. You may have sat down somewhere, and a bed bug crawled onto your coat. Consequently, you get home and throw your jacket on your bed. As a result, you have now introduced a bed bug into your home.

What To Do If You See A Bed Bug On Your Comforter In The Daytime

Consequently, the safest thing to do every time you come home is to isolate your clothing in a bag from a public place. You can even buy a heat box like the Zapp Bug or Thermal Strike. Both of these machines will heat your belonging to a temperature above 120°F. As a result, any bug on your clothing, suitcase, or backpack will be dead.

I use the ZappBug. However, I have gone to many clients’ homes who have the thermal strike set up, and they love it. The main thing about these heat boxes is that they give you peace of mind. No more worrying about picking a bed bug up on your coat or luggage; just put it in your heat box when you get home. The heat boxes help with bed bug anxiety.

Figuring Out How to Find Bed Bugs During the Day is Not an Easy Task

Even with all of my tools (bed bug sniffing dog, bright flashlight, microscope, and testing kits) often it’s not easy to find these bugs. A few years ago, Goosey and I searched an apartment on the Upper West Side of Manhattan, the residents were getting bites, and they thought they may have seen a bug but couldn’t be sure. Goosey alerted near the bed frame, and the client and I took apart the entire bed, aside from unscrewing the bed frame.

Unfortunately, we could not find any evidence; however, months later, he called me to thank me. The reason being is that he found where one of the clusters where they were living. After he began to unscrew each wooden piece of the bed frame, he saw fecal matter and shed skins between 2 pieces of wood. The two pieces were held together tightly by screws. The fecal matter and shed skins were not visible from the outside. However, that is precisely where our bed bug sniffing dog sat (her passive alert for bed bugs).
